OF HANCOCK, IOWA SEED THRASHEB Application led December 9, 1926.

My invention relates to improvements in seed thrashing machines in which a horizontal reel operates in conjunction with a striking bar; and the objects of my improvements are, first, to provide a means for knocking olf the seeds of growing and uncut plants; second, to provide yfacilities for raising and lowering the striking bar; third, to afford adjustment of the flail blades to proper contact with the seed pods; fourth, to provide a means for catching and holding the seed knocked off; and, fifth, to provide a means for unloading the seed readily from the machine. y

I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Fig. l is a side elevation of a seed thrasher constructed in accordance with the present invention.

Fig. 2 is a front elevation of the same.

Fig. 3 is a plan view of the seed thrasher.

Similar letters refer to similar parts throughout the several views.

An ordinary harvester wheel b is employed, which wheel runs on adjustable axle, the axle having the gear mv engaging the curved rack bw so as to lower the frame f by reason of a spiral orworm operated by the crank n. Attached to the frame f at the opposite end is the wheel/w which supports the outer end. Resting upon theframe f is a box or space g/ which is adapted to hold the seed and portions of the plants beaten off by the reel. A reel having the arm pieces 0 0, etc., is arranged to revolve in two arms supported on a pivot tn. At m and mf on the pivot n is supported two sprocket wheels gw, one of them carrying a chain y' running to the sprocket wheel onr the reel shaft a. An adjustable idler ml is provided to tighten the chain j. The chain h connects the sprocket wheel gwto the sprocket wheel cw upon the counter shaft c1'. n The sprocket wheel ma is arranged to engage by suitable clutch another sprocket wheel gy' on the shaft or. The sprocket wheel gj is connected by the chain z' to a sprocket m' which is attached to the wheel b. A clutch cl operates to engage the sprocket wheel cw to the sprocket wheel gj Serial No. 153,703.

upon a shaft d, which is operated by a lever fa having a rack 7', the leverpa being adapted to raise kand lower the reel vanes relative' to the striking board fb. Another lever c placed nearthe seat of the operator engages through the member Q9 the frame Zn to tip the frame and box Q/ with reference to `the tongue t so as to raise and lower the striking board fb with reference to the ground upon which the wheel b runs. A tongue t is arranged to be used with horses or tractor to pull the device along the ground.

When power is applied to the thrasherthe 'wheel b turns the sprocket ywheel ci which operates the sprocket gj. The mechanism is then thrown into gear by the rod gs operating on the rod Zto operate the clutch 0l which throws the sprocket wheel cw into motion. This operates through the chain h the sprocket wheel gw, and through the chain y' the sprocket wheel jw, turning the reel having the blades 0 0 0 0. The striking board fb bunches the plants in front of it and the reel blades o 0 o 0 strike the heads or seed pods of the plants and break them off, or shell out the seed, which is thrown to the rear into the box Adjustment is made by the lever a of the reel blades o o 0 o to the height of the plants to be seeded, while the lever 0 operates to place the striking board f?) at the proper distance from the ground. A door z is adapted to be opened in the rear of the* 4box y to take the seed therefrom.

In farming operations the use of sweet rclover as a. restorer of land has come to be used very generally. It is often pastured late in the season and is desirable to pasture it after it hasgone to seedQ By means of this machine seed may be taken from sweet soy clover left for pasture and then the whole y plant plowed under as a restorer of the soil.

Our invention is adapted to the taking of grains .or seed from any pla-nt where it is desirable to leave the plant standing upon the ground. Box y is unloaded at proper intervals and the seed taken from it and oarried away loy Wagons.

lVliat We desire to secure by Letters Patent is:

l. In a. seed thrasher, a pivotally mounted frame provided at its rear end with a seed receptacle, a striking bar carried by the frame and located at the front of the see/d reoeptaole, a pair of levers disposed approximately horizontally and fuloruined intermediate of their ends to form front and rear arms, -a rotary thrashing Wheel carried by the front arms of the said levers and cooperating with the striking bar7 gearing for rotating the thrashing Wheel, and means for adjusting the pivoted 4frame and the said levers for arranging vthe 'thrashing Wheel and the striking bar in proper cooperative relation.

2. In a seed thrasher7 a pivotally mounted irame provided at` its Vrear end with a seed receptacle, a striking bar carried by the vframe and located at vthe front of the seed receptacle, a pair oflevers disposed approximately horizontally and fulerumed intermediate of their ends lto form front and rear arms, a rotary thrashingk wheel carried by the front arms of the said levers and cooperating with the striking loar7 gearing for rotating the thrashing Wheel, compensating springs connected with the rear arms of the said levers, an adjusting lever connected with the rear arms of the levers vfor.adjusting the thrashing Wheel, and a separate adjusting rever connected with the pivoted frame for adjusting the striking bar.
